Laser For Endovenous Laser Ablation

What is Endovenous Laser Ablation (EVLA)?

Endovenous means inside the vein, a small amount of local anaesthetic is injected into the skin over the vein and a needle inserted into it. A wire is passed through the needle and up the vein. The needle is removed and a catheter (thin plastic tubing) is passed over the wire, up the vein and the wire removed. A laser fiber is passed up the catheter so its tip lies at the highest point to be heated (usually your groin crease). A large quantity of local anaesthetic solution is then injected around the vein through multiple tiny needle pricks. All staff and the patient put on laser safety specs as a precaution. The laser is then fired up and pulled down the vein over about 5 minutes. You will hear a warning buzzer ringing and may smell or taste burning but won't feel any pain. If you're having both legs treated the process is repeated on the other leg. The laser and catheter are removed and the needle puncture covered with a small dressing.

The treatment takes about 20-30 minutes per leg. You may also have some foam sclerotherapy or some avulsions undertaken and a compression stocking is then put on.

1470nm Absorption:

The 1470nm laser wavelength of CHERYLAS is effectively used in the treatment of the varicose veins, 1470nm wavelength is preferentially absorbed by water 40 times more than a 980-nm wavelength, the 1470nm laser will minimize any post-operative pain and bruising and the patients will recovery quickly and back to daily work in short time.

What happens after treatment?

Soon after your treatment you will be allowed home. It is advisable not to drive but to take public transport, walk or have a friend drive you. You will have to wear the stockings for up to two weeks and you will be given instructions about how to bathe. You should be able to go back to work straight away and get on with most normal activities.

You cannot swim or get your legs wet during the period in which you have been advised to wear the stockings. Most patients experience a tightening sensation along the length of the treated vein and some get pain in that area around 5 days later but this is usually mild. Normal anti-inflammatory like Ibuprofen are normally sufficient to relieve it.
